Schneider Electric Telemecanique Driver Pack up to 2.6 Device Driver system memory corruption

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Schneider Electric Telemecanique Driver Pack up to 2.6 (SCADA Software). It has been classified as critical. This affects an unknown code block of the component Device Driver. The manipulation of the argument system with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in the UnitelWay Windows Device Driver, as used in Schneider Electric Unity Pro 6 and earlier, OPC Factory Server 3.34, Vijeo Citect 7.20 and earlier, Telemecanique Driver Pack 2.6 and earlier, Monitor Pro 7.6 and earlier, and PL7 Pro 4.5 and earlier, allows local users, and possibly remote attackers, to execute arbitrary code via an unspecified system parameter.

The weakness was shared 11/04/2011 with Information and Communication Security Technology (Website). It is possible to read the advisory at This vulnerability is uniquely identified as CVE-2011-3330. The exploitability is told to be easy. Attacking locally is a requirement. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit.
